What’s behind the increase in lithium-ion battery fires on planes?

Though airline crews are trained to handle onboard emergencies, battery fires can be complicated, difficult, and dangerous to cope with.
A Li-ion battery contains volatile chemicals separated by a permeable membrane, explains K.M. Abraham, a professor at Northeastern University and a pioneer in Li-ion battery design. If that membrane is compromised—whether because of a defect or damage to the battery—the energy can be released in an uncontrolled manner, a condition called thermal runaway.
